Situation and medium-term forecast
Wintry conditions slow down pollination!
Low temperatures and depending on the height above sea-level even snowfall is expected during the first half of this week which is not beneficial for pollination. However, pollen allergy sufferers should avoid areas where hazel trees or bushes are located because the catkins that are already fully developed will also release pollen in the current not ideal conditions.
The flowering period of Spaeth’s alder has passed in the eastern parts of Austria. In regions that were not as thermally favoured, the catkins may still have some flowering potential left. According to the current weather forecast the native alder species will reach readiness to flower earliest at the end of the month.
What else: The pollen spectrum contains also pollen from cypresses and yews.

Note: The model results give an indication of the expected start of flowering, based on information provided by local pollen warning services with direct reference to the local situation. Start of flowering is not to be equated with the beginning of the pollen season. When the start of flowering is achieved, the majority of the plants have the potential to release pollen, but only when weather conditions are favourable.
